Polished Glass Prism with smooth, ground edges. 3" long with 3 equal 1"sides. Equilateral prisms are meant for dispersing elements, or white light, into a spectrum of colors creating a rainbow effect. Great for science experiments to demonstrate bending light. With 3 equal sides at 60 degree angles, there are 2 spectral diffractions. They can also be used for wave length separations, and special rainbow lighting effects in photography.
